Cloud Computing Exam Notes

Introduction to Cloud Computing

Cloud computing offers an alternative to on-premises data centers, shifting the responsibility of hardware purchase and maintenance to a cloud vendor. Users can rent required services, paying based on usage. It provides an accessible online portal for managing compute, storage, network, and application resources.

Key Cloud Service Providers:

• Microsoft Azure
• Google Cloud Platform
• IBM Cloud
• Amazon Web Services (AWS)
• VMware
• Joyent
• Rackspace

Cloud computing delivers computing resources as a service, managed by the cloud provider, including:

• Browser-based software applications (e.g., TikTok, Netflix)
• Third-party data storage (e.g., iCloud, Dropbox)
• Third-party servers for business, research, or personal projects

It allows businesses and consumers to access on-demand computing resources via the internet, eliminating the need for individual software and hardware maintenance. This shift drives cloud-based businesses and transforms IT practices.

Cloud computing delivers various services through the Internet, such as data storage, servers, databases, networking, and software. Users can access data and software programs from remote databases as long as they have web access. Benefits include cost savings, increased productivity, speed, efficiency, performance, and security.

Advantages of Cloud Computing

• Cost: Reduces capital costs by eliminating the need to buy hardware and software.
• Speed: Resources are accessible within minutes with a few clicks.
• Scalability: Resources can be adjusted based on business needs.
• Productivity: Less operational effort is required as patching and hardware/software maintenance are handled by the provider.
• Reliability: Data backup and recovery are fast and inexpensive for business continuity.
• Security: Cloud vendors offer a broad set of policies, technologies, and controls for data security.
• On-demand self-service: Access cloud resources without human interaction, gaining immediate access upon sign-up.
• Broad network access: Access cloud services through any device and networked location with permission.
• Resource pooling: Cloud provider resources are shared by multiple tenants, keeping data isolated.
• Rapid elasticity: Cloud resources can be rapidly increased or decreased based on changing needs.
• Measured service: Usage of cloud resources is metered, and users pay only for the resources they use.

Cloud Computing Challenges

• Cloud Security: Risk of data breaches, hacking of APIs and interfaces, and compromised credentials.
• Cost Management: Difficulty in predicting costs due to pay-as-you-go plans and fluctuating workloads.
• Lack of Resources and Expertise: Struggle to keep up with the demand for skilled employees.
• IT Governance: Difficulty in controlling provisioning and management of infrastructure operations.
• Compliance with Industry Laws: Managing compliance with industry regulations when transferring data to the cloud.
• Management of Multiple Clouds: Multi-cloud deployments can complicate addressing cloud computing challenges.
• Performance: Outages can disrupt business processes.
• Cloud Migration: Moving applications to the cloud can cause complications, take longer than anticipated, and exceed budget.
• Vendor Lock-in: Switching between cloud providers can cause technical incompatibilities, legal limitations, and substantial costs.

Evolution of Cloud Computing

Cloud computing involves renting computing services, originating in the 1950s. Key technologies include distributed systems, virtualization, Web 2.0, service orientation, and utility computing.

• Distributed Systems: Multiple independent systems appear as a single entity for resource sharing. Characteristics include scalability, concurrency, continuous availability, heterogeneity, and independence in failures. The main problem was geographical restrictions.
  • Mainframe Computing: Powerful, reliable machines handling large data and massive input-output operations. They have almost no downtime with high fault tolerance but are very expensive.
  • Cluster Computing: Machines connected by a high-bandwidth network. Cheaper than mainframe systems but still faced geographical restrictions.
  • Grid Computing: Systems at different geographical locations connected via the internet. Solved some problems but introduced new issues like low availability of high-bandwidth connectivity.
• Virtualization: Creating a virtual layer over hardware to run multiple instances simultaneously.
• Web 2.0: Interface for cloud computing services to interact with clients, enabling interactive and dynamic web pages (e.g., Google Maps, Facebook, Twitter).
• Service Orientation: Supports low-cost, flexible, and evolvable applications. Introduced Quality of Service (QoS) and Software as a Service (SaaS).
• Utility Computing: A computing model provisioning services like compute, storage, and infrastructure on a pay-per-use basis.

Parallel and Distributed Computing Systems

• Parallel computing and distributed computing terms are used interchangeably.
• Parallel Computing:
  • Tightly coupled system with homogeneity of components.
  • Multiple processors sharing the same physical memory.
  • Simultaneous processing of multiple tasks using multiple processors.
  • Utilizes divide-and-conquer technique.
  • Provides concurrency and saves time and money.
• Distributed Computing:
  • A collection of independent computers appearing as a single coherent system.
  • Each computer has its own local memory.
  • Computers communicate through message passing.
  • A single task is divided among different computers.

Why Use Parallel Processing

• Save Time and Money: Shortens the time for completion with potential cost savings.
• Provide Concurrency: Single computing resources can only do one task at a time.
• Serial Computing Limits: Transmission speeds depend directly upon hardware.

Shared Memory Architecture

  • Memory access across the link is slower.

Advantages of Shared Memory

• Global address space.
• User-friendly programming prospective to memory.
• Fast and uniform data sharing between tasks.

Disadvantages of Shared Memory

• Synchronization constructs the correct access to global memory.

Distributed Computing

• A distributed system is a collection of a large amount of independent computers that appear to its users as a single coherent system.
• Distributed Systems have their own local memory.

Advantages of Distributed Computing

• Memory is scalable with the number of processors.
• Processes can be accessed rapidly with its own memory without any interference.
• Cost-effective use of commodity processors and networking.

Disadvantages of Distributed Computing

• The programmer is responsible for many of these details associated with data communication between processes.
• Non-uniform memory access time data residing in a remote node to access local data.
